BRAKE, ABS, VDC OFF, SLIP light on.What do I do?
 

So I got 4 brand new tires put on today and after driving about a mile away from Tire Kingdom my BRAKE, ABS, VDC OFF, and SLIP Lights came on and wont go away. If I turn the car off and back on it will go away until I drive about a mile. Did Tire Kingdom mess up? Should I take my Z to the dealership? I am completely clueless. Please help!:icon14:

Check your brake fluid level

What size tires did you get?

i checked the brake fluid level and it looks fine. I guess i can add some to top it off. i know i got 40r in the front when it says to get 50r. could that really be the problem? i thought of that but to set off all those lights is a little extreme i think. BTW For the rear tires i got 45r which is what the car calls for.

The car is finicky about having enough brake fluid.
Just make sure it's at the top

Did they not resync your TPMS after installing the new tires?

Can you give us the exact tire size for front and rear. If the diameter difference between and front and rear aren't close to being the same, it will throw off the traction control/abs.. ect.

I wanna say I got 225-40r-18 on the fron and 225-50r-18 on the back

You can't go outside and look real quick? That is a crazy size tire on the rear, you sure thats right? I'm think the diameter differences are causing your traction control to go crazy....

It's obviously a tire problem. You changed your tires to the incorrect size and the lights went on within a mile, what else can it be?

Front should be 40 rear should be 35. That's the reason ur traction control is failing.

One of your wheel speed sensors could of been damaged.

That's not true, lots of people run different sizes than that.. some run 35 front, 30 rear, 30 all the way around, ect.. The key is the fronts and rear need to be close to the same diameter... If he is running a 40 front and 50 rear, his rears are probably over 1" bigger in diameter, thus causing his problem.

IDK why he starts a thread asking for help and can't even give us simple info like what size tires he had installed... :confused:

ROFLMAO Apparently that's waaaayyyy too much effort to make to solve such an insignificant problem.

Sorry I was at work when I guessed my sizes. rear is actually 45 and front is 40

I don't know if it helps but when I got my spacers installed they actually ended up torching my studs or something and burnt one of my 'speed sensors'..? That caused all of those lights to go on for me until they replaced it. Of course, I had a CEL as well and they checked it through reading that

I just swapped out base brakes with Sport Calipers and Spec R springs and the same thing happened to the car when I was done. We topped off the brake fluid the disconnected the (-) terminal on the battery for 45min to reset the ECU. The lights went away, then came back. The car was driven for a wile and the lights went off on there own. I never touched the wheel sensors during my work, I have no idea why the lights came on, I think the ECU just needed time to learn the new setting it is getting from the new input from the sensors.

Now we have the E-Brake light coming on when we shift from 3rd to 4th gear. Crazy Cars these Z's.

Everything in the manuals points to ABS wheel sensors. For the Slippery/VDC dash lights. The tire pressure light probably means they damaged one of your TPS senors when the removed the tires. Most shops can reset the TPS to your car. Dealer charges 25 to 50 to reset them depending on the dealer being a good one or crap.

I know that it might be a little late on this post but i just experinced the same problem. OEM tire sizes are 245-40R19 in front and 275-35R19 in the back. If you put a taller tire in the back then smaller in the front it will throw these codes. I had 245-40R19 in the front and 275-45R19 in the back and it threw Brake, Abs, VDC and slip. When you first start the car it wont thorw the codes until you drive at a consistent speed and the computer can sense that there is a problem. I put 275-35R19 in the rear and havent had the problem since. it was a costly mistake on my part
